Description
Technical field
The present invention relates to water-treatment technology field, is to be related to one kind to be used for the separated parallel channels of liquid more specifically
Outer press mold and its membrane module.
Background technology
Sewage disposal is carried out using membrane technology, particularly hollow-fibre membrane or tablet membrane technology, is current sewage disposal neck
The core technology in domain, and the technology being most widely used.For flow channel for liquids, runner generally cylindrical in shape do not have dead angle and
Flow resistance is smaller, and for the runner of other cross sections, liquid flowing is more smooth.Press mold is main outside common cylindrical shaped runner
Form is the outer press mold of doughnut, has been widely used in the fields such as environmental protection and water process at present.
In recent years with membrane technology and the integrated development of other technologies, hollow-fibre membrane product is proposed many new
It is required that.Many fields as associated with membrane technology and biotechnology, to improve the efficiency of sewage disposal, it usually needs improve activity
The concentration of sludge, meanwhile, to meet investment, taking up an area and safeguarding simple etc. requirement, and need to shorten whole sewage disposal
The flow of technique, then simplifies the pre-treatment to hollow-fibre membrane water inlet.Then, sewage with suspended active sludge is into film
It is easy to form deposition between film wire during filtering, causes film wire to pollute severe.Although plate membrane is in anti-high sludge
It is more advantageous than hollow-fibre membrane in terms of concentration, but its filling area is smaller, integrated equipment size of the same area is big, safeguard into
This height.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided a kind of parallel channels
Film and its membrane module.
Parallel channels film of the present invention, is achieved by following technical proposals, and a plurality of cylindrical channel is put down along same plane
Row arrangement, above-mentioned a plurality of cylindrical channel outer wrapping separating layer outer wall.
The a plurality of cylindrical channel number is 4-10 bars.
The cross-sectional circumference side of the parallel channels film is made of straight line or by the mellow and full company with periodicity concaveconvex structure
Continuousization curve is formed.
Parallel channels membrane module of the present invention, is achieved by following technical proposals, and a plurality of parallel channels film is along its runner
Direction is arranged in parallel, and also keeping parallelism arranges between each plane of parallel channels film arrangement, is set outside a plurality of parallel channels film outer
Shell, shell both ends are poured into a mould.
A plurality of parallel channels film number is 6-12 bars.
Compared with prior art, the beneficial effects of the invention are as follows：
Compared with existing doughnut membrane technology, the deposition that film product of the present invention can effectively avoid between film wire is asked
Topic, so as to improve the antifouling property of film product；Compared with existing tablet membrane technology, film product of the present invention has higher
Packed density, so as to assign the disposal ability of equipment higher.
Brief description of the drawings

Fig. 2 is parallel channels film cross-section curve appearance schematic diagram of the present invention；
Fig. 3 is parallel channels membrane module cross-sectional view of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.It is it should be appreciated that described herein
Specific embodiment only to explain the present invention, be not intended to limit the present invention.
As shown in Figs. 1-2, a plurality of cylindrical channel is arranged in parallel along same plane for parallel channels film, above-mentioned a plurality of cylinder
Passage outer wrapping separating layer outer wall.The a plurality of cylindrical channel number is 4-10 bars.The cross-sectional circumference of the parallel channels film
While (see Fig. 1) is formed by straight line or is made of (see Fig. 2) the mellow and full serialization curve with periodicity concaveconvex structure.
The parallel channels film is crowded with common solution (or melt) runner exit by being managed with parallel core liquid (gas)
Go out prepared by die orifice.The solution or melt can be the solution-polymerized SBR or melt spinning film forming feed liquid of different formulations.Fluid squeezes
Again by cooling or coagulating bath etc. are cured, pore-forming obtains after going out.
Parallel channels membrane module is as shown in figure 3, a plurality of parallel channels film is arranged in parallel along its runner direction, parallel channels film
Also keeping parallelism arranges between each plane of arrangement, sets shell outside a plurality of parallel channels film, shell both ends are poured into a mould.It is a plurality of
Parallel channels film number is 6-12 bars.
The membrane module its water inlet, production water and concentrated water direction should all be parallel with press mold outside parallel channels.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
